摘要
建立了水下拖曳柔索系统的三维有线段模型,该模型由一系列具有不同物理特性的铰接刚性杆组成,缆索可以包含多个开环或闭环分支。讨论了流体阻力、流体附加质量和流体静压力的影响,分析比较了附加质量与系统本身惯性的关系。该模型可用于水下拖曳系统的动力学仿真。
A three dimensional finite segment model for towed and tethered cable system is established.This model consists of s series of pin connected rods which may have different physical properties and the cable may have many open or closed branches.Effects of fluid drag,added mass and buoyancy are discussed.The comparisons and analysis are made between the added mass forces,moments and the inertia of the system itself..This model is expected to be applied to the dynamical simulation of the marine towed and tethered cable system.
